Description

Technical Field

[0001] The utility model relates to the technical field of ventilation for kitchen waste treatment, and in particular to a ventilation and deodorization system for a kitchen waste treatment workshop. Background Art

[0002] In the kitchen waste treatment workshop, due to the accumulation and decomposition of a large amount of food residues and kitchen waste, the foul smell and unpleasant odor seriously pollute the air quality, affecting the health and work efficiency of the staff. These odors may also spread to the surrounding areas, causing complaints and dissatisfaction from surrounding residents, seriously affecting the quality of life and regional environmental sanitation. Therefore, ventilation and deodorization equipment must be installed in the treatment workshop to deal with the odor.

[0003] Most of the existing ventilation devices rely on fans to extract indoor air, transport it to the deodorization equipment for deodorization, and then discharge it to the outdoors. However, the existing equipment has some shortcomings in use. For example, the wind pressure is insufficient when extracting air, which easily causes the odor to overflow from the location with low wind pressure, causing odor backflow and leakage. In addition, the existing deodorization method is to adsorb through materials such as activated carbon, which is effective when filtering solid particles, but has low processing efficiency for other odor sources. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a ventilation and deodorization system for a kitchen waste treatment workshop, which solves the problems of odor easily flowing back from the exhaust port and low deodorization efficiency.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a ventilation and deodorization system for a kitchen waste treatment workshop, comprising a deodorization shell and an exhaust shell, a connecting pipe is provided on the top of the deodorization shell, and the deodorization shell is connected to the exhaust shell through the connecting pipe;

[0006] An air inlet channel and a conveying channel are provided inside the exhaust housing, a fan is provided inside the air inlet channel, and the fan is used to draw air in the workshop into the exhaust housing, one end of the air inlet channel is connected to the conveying channel, and a one-way valve is provided at one end of the air inlet channel connected to the conveying channel;

[0007] An adsorption chamber and a water-soluble chamber are provided inside the deodorizing shell. A deodorizing mechanism is provided inside the adsorption chamber for adsorbing particulate foreign matter. An air pipe is provided at the bottom of the adsorption chamber, and the adsorption chamber is communicated with the inside of the water-soluble chamber through the air pipe.

[0008] Furthermore, a slidable movable sleeve is provided at one end of the connecting pipe, a flange is provided at one end of the movable sleeve, and the movable sleeve is connected to one side of the exhaust housing.

[0009] Furthermore, one end of the gas delivery pipe located inside the water-soluble bin is fixedly connected to a partition plate, and the partition plate is used to disperse the air in the gas delivery pipe.

[0010] Furthermore, a water inlet pipe and a drain pipe are provided on one side of the deodorizing shell, and both the water inlet pipe and the drain pipe are communicated with the interior of the water-soluble bin, and the water-soluble bin is used to absorb soluble foreign matter.

[0011] Furthermore, an exhaust hole is provided on the top of the deodorizing shell, and the exhaust hole is communicated with the interior of the water-soluble chamber. An adsorption plate is plugged into one side of the deodorizing shell, and the adsorption plate is used to adsorb foreign matter volatilized in the water-soluble chamber.

[0014] The ventilation and deodorization system of the kitchen waste treatment workshop of the utility model is arranged through the coordinated arrangement of the air inlet channel, the fan, the conveying channel and the one-way valve. When the air in the workshop is extracted, the odor can be sucked into the air inlet channel by the fan, and then conveyed to the conveying pipeline to the deodorization equipment for deodorization.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1 As shown, a ventilation and deodorization system for a kitchen waste removal workshop in this embodiment includes a deodorizing shell 1 and an exhaust shell 2. A connecting pipe 3 is provided on the top of the deodorizing shell 1, and the deodorizing shell 1 is connected to the exhaust shell 2 through the connecting pipe 3.

[0021] like Figure 2 As shown, an air inlet channel 4 and a conveying channel 5 are provided inside the exhaust shell 2. A fan 6 is provided inside the air inlet channel 4. The fan 6 is used to draw the air in the workshop into the exhaust shell 2. One end of the air inlet channel 4 is connected to the conveying channel 5. A one-way valve 17 is provided at the end of the air inlet channel 4 connected to the conveying channel 5.

[0022] like Figure 3 As shown, the interior of the deodorizing shell 1 is provided with an adsorption chamber 7 and a water-soluble chamber 8. The interior of the adsorption chamber 7 is provided with a deodorizing mechanism for adsorbing particulate foreign matter. An air pipe 9 is provided at the bottom of the adsorption chamber 7, and the adsorption chamber 7 is communicated with the interior of the water-soluble chamber 8 through the air pipe 9.

[0023] During use, the fan 6 in the exhaust housing 2 rotates to draw the odorous air in the workshop into the air inlet channel 4, thereby increasing the wind pressure in the air inlet channel 4 and pushing open the one-way valve 17 connected to the conveying channel 5, so that the air enters the connecting pipe 3 along the conveying channel 5, and is then conveyed to the deodorizing housing 1 by the connecting pipe 3 for deodorization. The deodorizing mechanism in the adsorption bin 7 is detachable and can be replaced after a long period of use. At the same time, the deodorizing mechanism is a composite material composed of activated carbon, coconut shell carbon, etc. The air adsorbed by the deodorizing mechanism will enter the water-soluble bin 8 along the air delivery pipe 9. Adsorbent is added to the water-soluble bin 8 to process substances that are not easily adsorbed but easily soluble in water. When the fan 6 in the exhaust housing 2 is accidentally damaged and shuts down, the one-way valve 17 is closed due to the reduction in wind pressure, thereby preventing the odor in the conveying channel 5 from flowing back out from the air inlet.

[0024] In this embodiment, a slidable sleeve 10 is provided at one end of the connecting pipe 3, and a flange is provided at one end of the sleeve 10, and the sleeve 10 can be connected to one side of the exhaust housing 2. The sleeve 10 can be extended and retracted at one end of the connecting pipe 3, which is more convenient when installing the exhaust housing 2. The position of the sleeve 10 can be adjusted so that the sleeve 10 can be better connected to the exhaust housing 2.

[0025] In the present embodiment, a separation plate 11 is fixedly connected to one end of the air supply pipe 9 located inside the water-soluble bin 8, and the separation plate 11 is used to disperse the air in the air supply pipe 9. A water inlet pipe 13 and a drain pipe 14 are also provided on one side of the deodorizing shell 1. Both the water inlet pipe 13 and the drain pipe 14 are communicated with the interior of the water-soluble bin 8. The water-soluble bin 8 is used to adsorb soluble foreign matter. An exhaust hole 15 is provided on the top of the deodorizing shell 1. The exhaust hole 15 is communicated with the interior of the water-soluble bin 8. An adsorption plate 16 is plugged into one side of the deodorizing shell 1. The adsorption plate 16 is used to adsorb foreign matter volatilized in the water-soluble bin 8. The air passing through the adsorption bin 7 will enter the water-soluble bin 8 along the air pipe 9. A plurality of air outlets are provided at the bottom of the partition plate 11 at one end of the air pipe 9, which can break up the air discharged from the air pipe 9 so that the gas can better contact with the solvent in the water-soluble bin 8. The water inlet pipe 13 and the drain pipe 14 are used to replace the solvent in the water-soluble bin 8. The solvent in the water-soluble bin 8 needs to be replaced after a period of use to ensure better adsorption capacity. An observation window is provided on the side of the deodorizing shell 1, through which the condition of the solvent in the water-soluble bin 8 can be checked. After the solvent absorbs the odor, it may volatilize the odor. The adsorption plate 16 absorbs the odor emitted by the solvent in the water-soluble bin 8 to further reduce the odor of the gas discharged into the air.

[0026] In this embodiment, a cover plate 12 is provided on one side of the deodorizing housing 1, and one side of the cover plate 12 is communicated with the interior of the adsorption bin 7. The cover plate 12 is used to replace the deodorizing mechanism. The cover plate 12 shields the deodorizing mechanism, and a stop block is provided on the inner wall of the adsorption bin 7. The deodorizing mechanism is arranged on the stop block, so that the filtered air can enter the air delivery pipe 9 from the hole at one end.

[0027] When applying the ventilation and deodorization system of the kitchen waste treatment workshop of the present embodiment: first, install the exhaust shell 2 to the required position, adjust the position of the movable sleeve 10, and use the connecting pipe 3 to connect the deodorization shell 1 and the exhaust shell 2 together; then, install the deodorization mechanism in the adsorption bin 7, and open the water inlet pipe 13 at the same time, and add the adsorption solvent into the water-soluble bin 8; after the adjustment is completed, start the fan 6 to draw the air in the workshop for deodorization; after using it for a period of time, open the cover 12 to replace the deodorization mechanism, and open the drain pipe 14 to discharge the solvent in the water-soluble bin 8, and add the solvent into the water-soluble bin 8 again.
